We're dividing 35995 by 3 
The aim is to understand the frequency of 3 in 35995.

Going ahead to step 1:
3 divided by 3 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Moving on to step 2:
If we divide 5 by 3, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 3 from 5 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

On to step 3:
When dividing 29 by 3, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtract 27 from 29 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Let's proceed to step 4:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
The remainder is 2 after subtracting 27 from 29.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Moving on to step 5:
If we divide 25 by 3, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 11998.0
Subtract 24 from 25 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 11998.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 11998.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 11998.33 and a remainder of 0.001.
